EYEGLASSES.

Specification of Letters Patent.

Patented Sept; e1, 1915.-

Application filed March 14, 1910. Serial No. 549,143.

To all whom it may concern:

Be it known that I, J osnrn F RIEDLANDER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented new and Improved Eyeglasses, of which the following is a full, clear, and exact description.

-This invention relates to eyeglasses, in which spring-controlled nose clips are pivotally secured in place and have associated therewith means by which they can be manually operated, my improvements residing primarily in the means for mounting the nose clips in position, and in controlling their movement.

One object of my invention is to facilitate the adjustment of the tension of the springs which control the pressure of the clips against the nose, whereby the proper adjustment may be made both when assembling the parts and when making changes in the clips or other parts.

A further object is to simplify the struc ture of the bridge and at the same time to facilitate the removal of the spring with the lever by utilizing a part of the lever which carries the clip or a wall on said lever to effectively conceal and hold the spring.

A further object is to more effectively hold the lever and spring in place by de tachably telescoping a retaining member with a post which is rigid on the bridge and which rises from a plate portion of the latter.

Other objects and advantages will be set forth more fully hereinafter and the several. novel features defined in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a front elevation of a pair of eyeglasses having an embodiment of my invention applied thereto, parts of the lenses being broken away; Fig. 2 is a perspective view of a lever and a nose clip of my invention, Fig. 3 is a plan view of part of a pair of eyeglasses, showing a lever and a nose clip; Fig. 1 is an enlarged vertical section of a barrel, showing the spring for controlling one of the levers; Fig. 5 is a plan view of a blank from which one of the levers is formed, and having a barrel for a spring associated therewith; Fig. 6 ,is a

plan view of a part of a lever, detached from, the pivot; Fig. 7 is a perspective view of one of the springs; Fig. 8 is a View similar to Fig. 3, showing certain details of modified form; Fig. 9 is a transverse section on the line 9-9 of Fig. 8; and Fig. 10 is a plan view of a lever of modified form.

Before proceeding to a more detailed ex: planation of my invention, it should be clearly understood that the invention relates solely to the clip and the means for supporting, controlling and operating the same, and that the structural details of the lens mounts form no part of the invention and can be varied in accordance with individual preference and special conditions, without departing from the underlying spirit of the invention.

Referring more particularly to the drawings, I have shown for example, a pair of eyeglasses having a bow or bridge 1, the opposite ends 2 of which extend outwardly in diametrically opposed directions, and are substantially in alinement. The bow, beyond its outwardly extending portions 2, terminates in lens mounts or clamps 31, which carry the lenses 32. The bridge ends have enlargements 3, which carry levers 5. The levers extend horizontally across the terminals, or outwardly extending portions 2 of the bow, and each lever has rigidly secured thereon, or formed integral therewith, a spring chamber preferably in the form of a barrel or cup fic- This is substantially cylindrical in form and extends upwardly from the lever. The enlargements 3 of the bow extensions have posts 6 which are preferably tubular, and extend through central openings 7 of the barrels. Spiral springs 8 are located within the barrels and encompass the posts.

In the form of the invention shown in Figs. 1, 2, 3, 4, 5 and 6, the barrels, at the upper edges are provided with pluralities of notches 9, which receive the upper, extended and laterally disposed extremities 10 of the springs 8. The bottoms of the barrels have cutaway parts 11 through which the lower, extended and laterally disposed ends 12 of the springs pass to enter openings 13 of the extensions 3. The extremities of the springs are thus anchored, andthe springs therefore tend to hold the barrels, and the lovers associated therewith, in normal position, as will appear more clearly hereinafter.

The levers, at the front ends have laterally and disposed at right angles thereto. arm also has 'a part 30 disposed at an acute disposed parts of any suitable form, which constitute finger grips 14, by means of which the levers can be manipulated. The springs tend to force the finger grips apart, and correspondingly to advance the opposite ends of the levers toward each other. The opposite ends of the levers carry the nose clips 15, and the springs thus serve to cause the nose clips to ,grip securely at the bridge of the nose of the wearer of the glasses. By pressing the finger grips between the fin gers, the nose clips can be separated, to permit the glasses to be taken from the nose, or

to be placed in position in the usual mannerv and maybe of any suitable form.

The posts 6 have heads 17 at the upper ends, which extend laterally toward the walls or the barrels, and are secured upon the posts preferably by means of retaining screws 18. The heads assist in'holding the springs in position, and also act as guides for the barrels. They permit the barrels to rotate freely, but prevent lateral and inclined movements of the barrels in the operation of the levers.

The levers 5, at the ends remote from the finger grips may be secured to the clips in any suitable manner. The particular means shown ismade the subject matter ofa divisional application, Serial No. 618,108, filed March 31, 1911. As illustrated, the levers have extensions 19 connected by reduced necks20, with extensions 21. A lateral extension 22 is connected with each extension :19, by a reduced neck 23. The extensions 19, 21 and 22 form leaves for the attachment of the nose clips. They are laterally bent so that theleaves 19 and 21 are parallel though spaced, and can receive between them an eiid 24 of an arm 25 associated with each nose clip 15. The leaves have threaded openings 26 therethrough, which receive .a correspondingly threaded retaining screw 27. The'lea'f 22 is folded back against the leaf 19, a'nd'in this way I provide a double depth of an ,o'pening 26 for the end of th'e screw, This'ins'ures a substantial depth of threaded opening, and permits the parts to be securely held together by the retaining Theneck 2'0 has an opening or'slot 28,

which is formed to receive a stopp.r'ojection ,2 9.of1the part 24 of thearm 25. The stop .29'limits'thepivotal movement of the arm 25 about the screw 27, if the'latter is loose. By lvarying the size. of the stop 29, the

amount of movement of the arm can be regulated.

The arm 25 hasthe part 24 laterally offset The angle, andextending diagonally with respect to the length of the clip 15. It is secured to thevclip, near the l'owerend thereof,"'a's is clearlysh'o'wn in Fig. 2. 'Themateglasses.

rial, metal being preferably employed, from which the clips and the arms are formed, permits them to be bent relatively to one another, so that the clips can be adjusted to fit exactly the nose of the wearer of the The angular disposition of the parts 25 and 30 of the arm, and the diagonal arrangement ofthe-part 3O relative'to the clip, facilitates and enlarges the scope of the adjustment of the clips. v

In Figs. 8 and 9 I have shown a modified form of connection between the clip and lever and which is also claimed inthe divisional application above referred to. this form I show levers 33, similar to the levers '33, as illustrated in Fig. 10.

The nose clips 39 have pairs of arms 40 and 41. The arms 40 have extensions 42 and 43 forming leaves provided with threaded openings. The leaf 43 is folded'back upon the leaf 42, and both extend at substantially right angles to the clip. The leaf at the end of the arm 41 is spaced from the leaf 42 and'is also provided with a threaded opening. The extension 37. at the end of the lever 33, is received between the leaves 41 and 42, and has an opening through which passes the retaining screw 44 which is located in the threaded openings of the leaves. The levers 33 have finger grips 36, and barrels 38 in which are mounted the springs 8. The upper ends of the springs are located in edge recesses 9 of the barrels, and the'lower ends which extend tangentially from the body of the springs, project through slots '45 in the barrel walls, and have downwardly disposed extremities located in the openings 46 of the bridge extensions 2. The slots 45 are elongated sufficiently to permit the barrels to move freely when'the levers are operated. The lower spring ends are introduced into the openings through slots 47 connected with the slots 45, and extending longitudinally ofthe barrels, to the upper edges thereof. In this way, the lower ends of thesprings can be anchored at-points outside of the barrels, as is shown most clearly in Fig. 8. It will be understood that the springs are arranged about posts 48 similar'to the posts 6. This form of the eyeglasses is substantially a-re- ,versal in certain details, of the form shown for example in Fig. 2. In the latter, each lever '55 has the leaves between which the part 24 of the clip-carrying arm is arranged.

In' t'he other form, the clips themselves have and at the other an extension 37, by means of which it carries the nose clip. The barrel has a slot 38 in the bottom thereof, concentric with the opening 35, and serving to permit the engagement of the lower end of the spring with the bridge extension.

In the preferred form of the lever, the cutaway part 11 is connected with the central opening for the post, as is shown in Fig. 6.
